Any amplifi er parameter is controllable using the serial RS232 interface. The RS232 protocol is outlined in the
following section and encompasses both the amplifi er and connected keypads.
The interface is bi-directional, allowing the amplifi er and network to be monitored.
The RS232 port connection must be made using a ‘Null Modem’ cable, where pin’s 2 & 3 are swapped at one
connector.
Fig 6 shows a typical touch panel controller providing the user interface to a 450 series amplifi er.
The controller has it’s own operating system that is programmed to handle the RS232 protocol.
An automation system is not restricted to touch panels, it may be an extension of a home lighting, security, building
management, or other specialised home automation system.
The ‘Page Preset’ is a special preset that is invoked whenever there is a contact closure across the ‘PG’ and 0V
terminals. Each zone on the amplifi er may be set to a specifi c input and at specifi c volumes (depends on room &
application). When the contact closure is opened the amplifi er returns to its previous states. The ‘Page Preset’ is
useful for telephone paging, door & gate phone paging, or doorbell applications.
Note : The S8 input is summed with the internal doorbell generator
